2. A 10.0 g ice cube, initially at 0.0ºC, is melted in 100.0 g of water that was initially 20.0ºC. After the ice has melted, the equilibrium temperature is 10.93ºC. Show your work!

a. Calculate the total heat (in J) lost by the water (specific heat for water is 4.184 J/g°C).

b. Calculate the heat gained by the ice cube after it melts (specific heat for ice is 2.093 J/g°C).

c. Calculate the heat it took to melt the ice. (It takes 334.0 J/g of heat energy to melt ice). qmelt = mice ΔHmelt

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.

hi my dude or dudette

bcde is the incorrect answer it is a

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
